To all whom it may concern Be it known'that 1, MILES EDWARD LonnR, a citizen of the United'States, residing at Claypool, in the county of Kosciusko and State of Indiana,have invented certain new and useful Improvements in Acetylene-Grenerators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it This invention relates to new and useful improvements in acetylene gas generators of the type embodying essentially a generator, a gasometer, and carbid-feed mechanism automatically operable'by variation of volume of gas inthe gasometer for regulating the complished by such means as are illustrated in the accompanying drawings,- described in the following specification and then more particularly pointed out in the claimswhich are appended hereto and form a part of this application. v

With reference to the drawings, wherein I have illustrated the preferred embodiment V of my invention as it is reduced to practice,

. and throughoutthe several views of which similar reference numerals designate corresponding parts: Figure 1 represents a ver tical central sectional view, partly broken away, through the generator, Fig. 2 repre-' sents an enlarged sectional view, partly broken away, illustrating the carbid feed mechanism in detail, Fig. 3 represents a. detail view of the feed wheel employed in controlling the dispensing of carbid from the carbid-contain'er intothe generat ing chamber.

nate corresponding parts throughout the several views, the numeral" 11' indicates a cylindrical metallic shell orfcasing' which, if

desired, may'be mounted within an outer caslng (not shown) and the upper terminal.

of whichis open and; is equipped with the lid or cover 12 of thelusual sealing flange 11 is formed at its lower terminal with afunnel-shaped-mouth, as at 14:. b

The generating chamber, designated by theletter A, is arranged at'the lower end of the inner casing lland is formed by a secbeing secured in spacedv relation thereto by bolting, soldering, or otherwise securing the flared mouth or flange 34 to the casing 11. It will be apparent that an annular chamber, to be hereinafter designated by the letter B, isv formed between the members 11 and '33. In this chamber is arranged the gasometer which will be next described. I

The gasometer consists essentially in a gas bell 35, which is annular in shape and is formed by a pair of spaced annular walls 36 and 37, the upper edges of which are connected and sealed by a ring plate 38,

while the lowerportion of the bell is unsealed to permit'water which is in'practice 'ondary inner shell 33 having'a flared mouth or flange-34, which is cyli'ndricalin shape and is of less diameter than the member 11,

into the gasbell through a pipe 39, theupper F T end of which carries-a funnel-shapedfilter,

designated as an entirety in Fig. 1 by the numeral l0. The pipeis secured in position in -the member 4-0 by alayerof suitable porous filtering material 41. As illustrated f in detail in Fig. 5, this filter 40 is asub .stantially inverted funneleshaped shell, so

that as the gas issues from the upper end of the pipe 39 it must, before-entering the into the service pipe.

A service pipe22 is connected with a branch pipe 23 which latter is extended through the wall of the casing 11 and upwardly within the-gas bell 35, having its up per open end disposed-above the level of the water in said bell. The generating chamber A is adapted to be partially filled with water by a water pipe 17 extended through the lower portion of the wall of the cas- 70 ing 11. The gas bell is operatively connected to the-carbid-feed mechanism, so that the feeding of the carbid is automatically regulated by the variation of the volume of the gas in 75 the generating chamber. This carbid-feed mechanism is all arranged interiorly of a cylindrical casing 43, which is slightly greater in diameter than the casing 33 and is telescopically and rigidly secured thereon. S The casing 43 carries adjacent its lower end an internally arranged substantially funnelshaped shell 44, which may be welded, bolt- 7 ed, or otherwise secured in assembled position, and which is designed to support the 85 casing in assembled position on the member 33. As. illustrated in detail in Fig. 3, the apex portion of the shell 44 is provided with a closure plate 45, centrally of which is journaled the lower terminal of a feed shaft 90 46. On the shaft 46 is carried a feed wheel 47, which isarranged torotate with the shaft and to urge the carbid which is contained within the casing 43 to an opening 48 formed at one side of the plate 45. Be- 95 low the opening 48 is secured a tubular chute 49, the lower. end of which is normally closed by a pivoted gate valve 50, which carries a balance arm 51 and balance weight 52 adjustably mounted thereon 100with a set screw 53. The gate valve 50 is normally held in closed position by the balance weight 52, but when the shaft 46 has been rotated sufficiently to deposit the desired amount of carbid in the chute 49 the 105eifect of the member 52 is overcome, and the carbid drops into the generating chamber.

The member 52 may, of course, be adjust able on the arm 51 to effect the deposit of the carbid into the generating chamber in 110any desired predetermined quantities. In the preferred embodiment of this invention a pound of carbid is deposited in the generatin g chamber by the valve 50 as a charge. The shaft 46 extends vertically and cen- 115trally within the casing 43 and is journaled for the greater part of its length in a tube or sleeve 54, the upper terminal of which is secured, as at 55, centrally of a cover or top 56, and the lower terminal of which is se- 0 cured, as at 57 to an inclined partition plate 58, which forms a bottom wall for the carbid chamber C. Anvopening is formed in the member 58 and at one edge thereof, as at 59, to permit the carbid to pass from the 1 chamber C down the inclined wall of the partition plate 58 through the opening 59 and to the feed wheel 47. The top 56 is, of course, provided with an inlet, as at 60 to permit the operator to fill the carbid chamber in the usual manner.

The shaft 46 is designed to be rotated only during the dropping of the gas bell, so that while the volume is increasing in the generating chamber, the bell will move upward without causing the deposit of any more carbid in the generating chamber. As a means, therefore, for operatively connecting the gas bell to the shaft 46 in such man ner that the shaft will be rotated only upon the downward movement of the bell, there 1 has been provided a stub shaft 61, journaled at its upper terminal in a horizontal member 62 of a frame 63, mounted on the top 56. A pair of fusees 64 and 65 are keyed on the stub shaft 61and are adapted to 00- operate in winding the gas bell chains 66 and 67, when the gas bell moves upwardly under pressure. These two fusees 64 and may be formed integrally and are arranged oppositely as regards their relation to the stub shaft 61. The upper terminal of the shaft 46 extends through a bearing 68 upwardly into the lower fusee 65, in which it is freely jou'rnaled. A ratchet wheel 69 is secured to or formed integrally with an adjustable col lar 70, which is held in the; desired position. on the shaft 46 by a set screw 71. This ratchet wheel 69 is arranged for engagement by a pivoted pawl 72 which is pivotally secured to the lower face of the lower fusee 65. When the gas bell moves upwardly, the stub shaft 61 is rotated by the gravity pull of a weight 73, whichis operatively connected to the shaft 61 by a cable 74, which plays over a pulley 75 secured to the frame 63 and is designed to wind and unwind on a pulley 76, keyed on the stub shaft 61 adjacent its upper terminal. The pawl 72 is designed to move around the ratchet wheel 69 without positively engaging it during the rotation of the stub shaft 61 by the weight 73, during the upward movement of the gas bell, but when the gas bell again moves downwardly the pawl 72 positively engages the teeth of the ratchet wheel 69 and effects an operative connection between the. stub shaft 61 and the feed wheel shaft 46. 1 r V VVhen' the gas bell 35 moves upwardly the chains 66 and 67 which are connected to the gas bell and tothe fusees 64 and 65 are wound upon the fusees 64 and 65 hence the weight 73 connected with the stubshaft 61 is permitted a downward movement upon the slackening of the chains 66 and 67 thus causing the fusee 64 and carried upon the shaft 61 to rotate and subsequently wind the chains'thereon. VWhen the gas bell 35 moves downwardly owing to the decrease of erating chamber A. ea
